the OP asked for quiet and servicable lennox is at or near the top on both points.

Thanks. I am not aware of this. Last I heard on this forum, Rheem/Ruud is claiming to have the quietest gas furnaces and I don't think there is any outside unit easier to access then a Rheem/Ruud rectangular unit.

any lennox HS series is much easier to service than the rectangle units. lennox 10acc and 13 acc are a pain but we never sell bottom line units anyway

as far as furnaces go i don't see much differnce in noise with the sealed combustion and v drive blowers. all are very quiet

one thing you can be sure of. if NG is going up so is oil
in turn so will electic. the plus side is as high efiecieny as possible. heat pumps can give i believe 250percent or higher rateing. with 90plus backup you will be as far ahead as posible. as far as the savings and pay back goes depends on what the utility price level out at. to even think of useing last years costs for a comparisome would be futile.

I would be going duel fuel but I have always thought that If it were me I would look into adding strip heat besides the gas or propane with a heat pump. The way every fuel is going up , why not have the option of electric backup too. I dont know about ground source being what little I did with it when it first came out, it was real expensive and I dont think they were as good as they are now. Now those new Heat pumps for cold temperature look interesting but for the price the warranty on the compressors are only 5 years...for that price they should be at least 10, but its a heat pump running year round. Oil aaaahh I dont think so.

the only thing i dont like about lennox are them damb pure air cleaners. They make one size, and its quite large.And one more thing the mighty 21 seer. I will be on L&I soon if you customers keep buying them.
